Magnetoresistance effect device, magnetic head, magnetic recording apparatus, and memory device |
摘要 |
A magnetoresistance effect device includes: a free layer whose magnetization direction is easily rotated by an external magnetic field; a non-magnetization layer; and a pinned layer whose magnetization direction is not easily rotated by an external magnetic field, the pinned layer being provided on a face of the non-magnetization layer which is opposite to a face on which the free layer is formed, wherein the pinned layer includes: a first non-magnetic film for exchange-coupling; and first and second magnetic films which are antiferromagnetically exchange-coupled to each other via the first non-magnetic film, and the first non-magnetic film includes one of the oxides of Ru, Ir, Rh, and Re.
